Method
On a Monday evening card, the top of the shortlist is tight enough that the margin matters — so let me show my working. The engine today scanned all declared runners through a three-stage filter: first a race-state check to strip any abandoned or resulted races, then an odds band of 2.0–50.0 decimal (no odds-on, nothing at 50/1 or longer), then a field-size gate of 6–14 runners to cut out the noise of tiny fields and the chaos of big-field handicaps. Feature scores were assembled across seven dimensions — speed (weight 1.5), form (1.2), class change (1.0), trainer strike rate (0.8), going (0.8), market move (1.2), and draw (0.5) — with the heavier weights sitting on speed and market move, the two signals I trust most when the form book is ambiguous.
Today's universe
The day opened with 33 races and 290 runners. The race-state check dropped none. The odds filter moved the pool from 290 to 258, removing odds-on runners and anything drifting out beyond the 50.0 decimal ceiling. The field-size filter then cut from 258 to 207, keeping only runners in races with 6–14 declared starters. Those 207 runners formed the scored universe.
The shortlist
Five horses separated themselves from the pack. Switch From Diesel leads on 6.91/10, with Daler one step behind on 6.87/10 — a gap of just 0.04, which is as tight as these scores get. Wee Mary scores 6.60/10, Gemini Man 6.51/10, and Polka 6.48/10. The feature that ultimately tipped the balance for Switch From Diesel over Daler was the form score: +3.00 on a decay-weighted read of recent runs, against Daler's +0.77. Daler fights back hard on trainer strike rate (+1.19 for a hot G M Lyons yard at 26%) and a confirmed market steam (+2.00), but the form gap is too wide to bridge at this composite level.
Why this horse
The read I keep coming back to with Switch From Diesel is the combination of a high speed rating and a genuinely fresh win in the form string. The speed score is +1.26 — that is an SR of 92 against a field mean of 75.4, a z-score that puts her clearly ahead of what she is lining up against tonight at Ballinrobe. That speed edge, weighted at 1.5, does the heavy lifting in the composite. The form score of +3.00 — the highest on the entire shortlist — reflects a decay-weighted read of a recent winning run; the '1-' string tells me the latest run was a win, and the engine is crediting that with a +2.00 decay-weighted average before the weight multiplier is applied. That combination of speed and fresh form at the top of the leaderboard is what a marginal composite still has going for it.
The going score adds a quiet layer of confidence: 2-from-2 on good or adjacent ground, giving a going score of +1.00. She has not been asked to run on going that suits her and come up short — she has gone twice on comparable conditions and both runs were placed. Trainer Ross O'Sullivan's strike rate of 12% over the last 30 days (5/40) is on par rather than hot, contributing only +0.04, and there is no market move to read — +0.00 on that feature, meaning the books have not been troubled by money either way. The class data is unavailable for this race grade, so I cannot score a class-change edge. I note those absences honestly.
At 11/8 (decimal 2.375), she sits at the shorter end of the odds band. The price is not generous, and I would not be chasing it if it shortens further. But the composite of 6.91/10 — solid rather than strong, to be direct about it — is the best score the engine has produced today, and the feature profile behind it is built on two reliable signals rather than a single lucky number.
What worries me
The composite is 6.91/10: solid, but not a number that invites maximum confidence. The gap over Daler is just 0.04 points, and Daler has two things working in its favour that Switch From Diesel does not — a trainer firing at 26% in the last 30 days, and a confirmed market steam that the model scores at +2.00. If that money knows something, the steam argument for Daler is real. Class data is unavailable for both Irish races, which is a genuine gap in the picture; I cannot tell whether Switch From Diesel is dropping into a soft race or running against better company than her form was earned in. Draw bias is also unscored — the data layer is not yet built. No market move on Switch From Diesel means I have no late-money confirmation to lean on, only the form and speed signals. A change in going — Ballinrobe can ease quickly in June — would undermine the going score, though the race is currently declared on good ground.
